Personally, I've been looking forward to Huxley for forever now. An MMOFPS that plays like Unreal Tournament sounds awesome, and it will be on the PC and the 360, along with possibly the PS3. Too bad the beta is only in Korea.
Also, Freeworld looked really good, until I realized that it's in development and the developers abandoned it (kind of...read the forums).

Other than that, I guess I'll be waiting for Unreal Tournament 3, and Mass Effect. Ryzom was pretty much the only great mmo I've ever played.
...but then we all know that Ryzom will probably end up OK...hopefully...
